Chrysanthemum plant named ‘Yobaldwin’

ABSTRACT

A new and distinct cultivar of  Chrysanthemum  plant named ‘Yobaldwin’, characterized by its uniform and somewhat outwardly spreading plant habit; strong and freely branching growth habit; dark green-colored foliage; uniform flowering response and habit; can be grown as a spray-type or without bud removal; early flowering habit; anemone-type inflorescences with spoon to quill-shaped ray florets; purple-colored ray florets; and good postproduction longevity with plants maintaining good substance and color for about three weeks in an interior environment.

Botanical designation: Chrysanthemum×morifolium.

Cultivar denomination: ‘Yobaldwin’.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar ofChrysanthemum plant, botanically known as Chrysanthemum×morifolium andhereinafter referred to by the name ‘Yobaldwin’.

The new Chrysanthemum is a product of a planned breeding programconducted by the Inventor in Salinas, Calif. and Alva, Fla. Theobjective of the program is to create or discover new pottedChrysanthemum cultivars that are suitable for year-round production withuniform plant growth habit, good vigor and strong branching habit,numerous inflorescences, desirable inflorescence form and floret colors,fast and uniform flowering response, and good postproduction longevity.

The new Chrysanthemum originated from a cross-pollination made in April,2000 in Salinas, Calif., of a proprietary selection ofChrysanthemum×morifolium identified as code number YB-A2427, notpatented, as the female, or seed, parent with a proprietary selection ofChrysanthemum×morifolium identified as code number YB-A2333, notpatented, as the male, or pollen, parent. The new Chrysanthemum wasdiscovered and selected by the Inventor as a single flowering plantwithin the progeny of the stated cross-pollination grown in a controlledenvironment in Alva, Fla. in March, 2001. The selection of this plantwas based on its uniform plant growth habit, good vigor and strongbranching habit, desirable inflorescence form and floret colors, fastand uniform flowering response, and good postproduction longevity.

Asexual reproduction of the new Chrysanthemum by vegetative tip cuttingswas first conducted in Alva, Fla. in June, 2001. Asexual reproduction bycuttings has shown that the unique features of this new Chrysanthemumare stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Yobaldwin has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, daylength, and/or lightlevel, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Yobaldwin’. These characteristics incombination distinguish ‘Yobaldwin’ as a new and distinct Chrysanthemum:

-   -   1. Uniform and somewhat outwardly spreading plant habit.    -   2. Strong and freely branching growth habit.    -   3. Dark green-colored foliage.    -   4. Uniform flowering response and habit.    -   5. Can be grown as a spray-type or without bud removal.    -   6. Early flowering, 7.5 week response time.    -   7. Anemone-type inflorescences with spoon to quill-shaped ray        florets.    -   8. Purple-colored ray florets.    -   9. Good postproduction longevity with plants maintaining good        substance and color for about three weeks in an interior        environment.

Plants of the new Chrysanthemum can be compared to plants of the femaleparent selection. Plants of the new Chrysanthemum differ from plants ofthe female parent selection primarily in ray floret color as plants ofthe female parent selection have light pink-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of the maleparent selection. Plants of the new Chrysanthemum differ from plants ofthe male parent selection primarily in inflorescence form and ray floretcolor as plants of the male parent selection have daisy-typeinflorescences with red-colored ray florets.

Plants of the new Chrysanthemum can be compared to plants of thecultivar Yoplymouth, disclosed in U.S. Plant Pat. No. 14,717. Inside-by-side comparisons conducted in Alva, Fla., plants of the newChrysanthemum differed from plants of the cultivar Yoplymouth in thefollowing characteristics:

-   -   1. Plants of the new Chrysanthemum and the cultivar Yoplymouth        differed in inflorescence form as plants of the cultivar        Yoplymouth had daisy-type inflorescences.    -   2. Plants of the new Chrysanthemum flowered about three to four        days later than plants of the cultivar Yoplymouth.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The RoyalHorticultural Society Colour Chart, 1995 Edition, except where generalterms of ordinary dictionary significance are used. The aforementionedphotographs, following observations and measurements describe plantsgrown and flowered during the spring in Salinas, Calif., in afiberglass-covered greenhouse and under conditions which approximatethose generally used in commercial potted Chrysanthemum production.During the production of these plants, the following conditions weremeasured: day temperatures, 21 to 27° C.; night temperatures, 17 to 19°C.; and light levels, 5,000 to 6,000 foot-candles. Four unrootedcuttings were directly stuck in 15-cm containers, exposed to longday/short night conditions, and pinched once about two weeks later. Atthe time of the pinch, the photoinductive short day/long nighttreatments were initiated. Plants used for the description were grown asspray-types. Measurements and numerical values represent averages oftypical flowering plants.
